I brought my car in, which was under warranty for a squeeking noise in the front suspension. This was the second time the car was in at a Ford dealership and I told them when I brought it in, keep it until you fix it. They called me two weeks later and told me they fixed it, saying it was the airbox which was off a little causing the rubbing/squeeking. I found this a little odd because this sound was not coming anywhere near that. I got the car back and it was if anything squeeking worse than before!
